Abstract: | This work presents a tool for determining the spring constant of a helical spring using 1D and 3D finite element models. The aim is to develop an application that follows a methodology capable of calculating the spring constant based on the spring's geometric and mechanical properties. The study focuses on helical springs with circular cross-sections. The methodology involves creating the spring's geometry and discretizing it into finite elements using the Gmsh software. Two approaches are considered: a 1D model and a 3D model. The 1D model represents the spring as a series of beam elements, while the 3D model represents it as elements that form a solid volume. The Code_Aster software is used to solve the mechanical problem and obtain the results. Simulations are validated by comparing the calculated spring constants with the values provided by the spring manufacturers. The analysis includes variations in mesh size and considers different spring models to evaluate the convergence and accuracy of the results. The findings show that both the 1D and 3D models converge to the theoretical values of the spring constant as the mesh size decreases. However, the 3D model provides more accurate results at the cost of increased computation time. The 1D model offers a good balance between accuracy and efficiency. The work highlights the importance of mesh size for obtaining accurate results and identifies a balance between accuracy and computational cost. The critical aspects of the methodology are also discussed, and future lines of research are presented. This study provides a tool for determining the spring constant of a helical spring through finite element analysis. It offers insights into the accuracy, efficiency, and applicability of the models, laying the foundation for future developments that expand and improve the applications' capabilities. |
